The problem with your tree starts with the grade change around the base of
the tree. Actually if you would have built a well around the tree and
changed the grade beyond the well, it would have had a chance. If that tree
was there before the wall and fill, then I would say it is troubles in the
rhizosphere especially suffocation of the tree by reduction of free oxygen
at rhizoplane. Trees require oxygen for respiration. Filling in around a
tree like that greatly reduces free oxygen in rhizoplane. In that case it
may just be too late for the tree and trying to fix that very easily could
make things even worse. Trees do breath.

When was the grade changed?

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.
Some people will buy products they do not understand and not buy books that
will give them understanding.

My tree is dropping tons and tons of leaves. We've had a very wet
Spring and Summer here in NW Arkansas. Here is a link to some close-
ups of the leaves. The yellow detached leaves fell from the tree
today. The green leaves were pulled from the tree. I'm trying to
determine if I can treat the tree and make it stop dropping leaves. In
prior years it has dropped some leaves due to scorching I presume but
nothing close to this year. I appreciate your help.
